Demands for high data rate communication in an indoor environment require innovations on high speed and energy efficient channel equalizer designs. In this paper, we propose a `semi-analog' channel equalizer with high power efficiency and fast processing speed for 60 GHz channels. The proposed system consists of a channel estimator and a multipath canceler. The channel estimator uses a prolate spheroidal wave function (PSWF) with low peak-to-average power ratio (PAPR) to provide an accurate estimation of channel parameters, based on which the multipath canceler removes reflected signals due to multipath. We evaluate its performance in terms of bit error rate (BER) considering a real indoor propagation environment at 60 GHz.
